This invention relates to machines of great length divided into individual sections, particularly spinning machines (slubbing, roving, spinning or twisting frames) In general mechanical engineering, machines of great length are known to be divided into individual sections in order to facilitate the manufacture of the individual parts, their transportation and the assembly. Considering the great number of similarly operating devices incorporated in one and the same textile machine, it has also with textile machines become customary to make up such machines of sectional parts.

Prior to this invention, the idea of making up sectional textile machines has been carried out merely with a View to an adaptation to the number of working points available, but without regard to uniformity throughout, and the division of the machine into various sections has been made only for the purpose of attaining certain limited ends with respect to some individual machine parts, whereas the remaining machine parts have had quite a different length from that of the uniformly divided sections. For example, it has been the practice to divide the spindle rails and the driving shafts of ring spinning frames into sections of equal length in order to be able to construct machines of any desired length. It has also been proposed to divide the spindle rail into sections which are independent of one another, in order to compensate for any irregularities in the tension of the driving tapes for the spindles. Furthermore, machines are known in which longitudinal sections of one and the same type of elements have the same length while differing in length from different types of elements. For example, spinning machines are known having all roller beam sections of equal length, ring rail sections likewise of equal length but differing in length from said roller beam sections, and guide rod sections which, while or equal length among each other differ in length from said roller beam sections and said ring rail sections. Such machines also comprise spindle rail sections, driving shaft sections, drawing roller sections and the like which while of equal length among each other, differ in length from said roller beam sections, ring rail sections, and spindle rail sections.

Longitudinal sections of varying length such as referred to above are carried by machine frames and cross pieces which are distributed over the length of the machine merely from the points of View of Statics and strength. Due to these circumstances, the machines of conventional design form intrinsically rigid structures with but a very limited ability to follow such changes in stress as are due to influence of heat, operating thrusts, displacements of load, abrasion, giving way of the subsoil, and similar phenomena of a dynamic nature. Especially in the case of textile machines in which the material to be processed is highly sensitive even to negligible changes in the running of the machine, this is extremely bad and is always reflected in reduced output.

It is, therefore, an object of this invention to provide a sectional textile machine which will overcome the above mentioned drawbacks.

It is another object of this invention to provide a sectional textile machine construction in which all elements in one and the same individual machine section will be able to breathe evenly soto speak, i. e. any misalignment and re-alignment will be possible substantially under practically the same angular conditions and to the same extent for all sectional members of one and the same machine section.

These and other objects and'advantages of the invention will appear more clearly from the following specication in connection with the accompanying drawings, in which:

Fig. 1 is a partial longitudinal view of a machine in accordance with the invention, one individual section being shown separately for the sake of clarity.

Fig. la illustrates a coupling element interconnecting two shaft ends.

Fig. 1b is a section taken along the line Ib-Ib of Fig. la.

Figs. 2 and 3 are exaggerated illustrations indicating the mode of operation of the invention.

Fig. 3a is a cross section through Fig. 1 around a vertical column thereof.

General arrangement The present invention is based on the' nding that machines of great length should possess quite a specific dynamic yielding capability and flexibility enabling them to ada-pt themselves in a manner of a rope or the links of a chain to any dimensional changes which are due to mechanical or thermal factors, i. e. to breathe so to speak.

Accordingly, the present invention suggests that the sections of all horizontal parts of the machine should be of equal length, and the individual sections should be connected to each other in such a manner that their joints or end surfaces are located in the same planes. Ii so subdivided, the individual sections form, so to speak, the links of a chain, while the joints form the' hinge points of the links of such chain.

In order to assure this flexibility, it is further suggested to locate the bearings of the individual longitudinal sections in the planes of their joints or end surfaces. One feature of the invention serving the same purpose is that the guiding of the longitudinal sections moving up and down is likewise effected in the planes of their joints, and another feature of the invention consists in that the mechanisms which elfect the movement of the rising and lowering longitudinal sections are also located in the planes of their joints.

While these measures already afford a considerable amount of adaptability of the machine construction with respect to any displacements of parts as will occur under service conditions, this is still further improved by the feature suggesting an articulated connection of the longin tudinal sections themselves. This may be accomplished, for example, by means of uniformly shaped coupling members for all those longitudinal sections which have a circular' cross section. fis a result of such uniform couplings, all the longitudinal sections equipped therewith are compelled to yield simultaneously by the same amount in the event of dimensional changes in length, so that the whole assembly is allowed to breathe,7 that is to say, give way in a flexible manner so that ail longitudinal parts are affected evenly.

In order to further an even adaptation of the longitudinal sections in the event of any displacements or variations in length, another feature of the invention suggests that longitudinally divided parts should essentially have the same cross section if they are made from like materials.

Finally, when also locating the machine frames in the planes of the joints of the longitudinal sections, as suggested by the invention, the links of the chain are given an end support around which they are allowed to swing, and which support affords a simple levelling by designing the uprights so as to be adjustable in height in accordance with another feature of the invention.

Structural arrangement For purposes of illustrating the invention, a ring spinning machine having a vertically movable spindle rail with positively driven spindles and a xed ring rail has been chosen as an example. Of course, the invention is not confined to such machines, but is readily adaptable to other designs such as ring spinning frames with tape driven spindles, as well as other types of machines, e. g. twisting frames and preparing machines.

Referring now to Fig. l, the machine shown therein has a total length of approximately 20.5 yds. while, for the sake of clarity, the driving arrangements and those details of the drawing frame which are not absolutely necessary for the understanding of the invention, have been omitted. The machine is divided into individual sections designated I, Il, III and so forth which are arranged side by side and, by way of example, have a length of 1.09 yd. cach. Each section comprises the same number of supporting parts arranged horizontally, such as the top bobbin rail I, the thread guide rod 2, the bottom bobbin rail 3, the roller beam il, the lappet rod 5, the ring rail S, the spindle rail 1, and the treadle rod 8, as well as the same number of horizontal rotary longitudinal parts such as the rluted rollers 9, I and the front roller II of the drawing frame, the spindle driving shaft I2 and the lifter shaft I3 ofthe spindlevrail, which are carried in the respective bearings I4, I5, I5, I'I, i8, I9, or 23, 2|, 22, 23, 2li.

As will appear from Fig. l, the sections I, II. III of all the horizontal parts of the machine are of the same length, and the various sections are connected to each other in such a way that their joints always lie in the same planes A-A. Located in these planes are also the bearings I4 to i9, so that all longitudinal sections are supported at these points, thereby preventing any jamming, distortion and similar faulty stresses as are likely to occur with the bearings being arranged differently.

lt is just as advantageous to arrange the rising and lowering longitudinal sections, i. e. the spin die rail 'l in the example set forth, to be guided in the planes A-A of their joints. By locating the vertical guiding means in those planes, it is possible to eliminate any components of forces which might be produced if the guiding means were arranged at some other points of the machine franie, and which might interfere with the operation of the machine in the event of negligible displacements of its longitudinal parts, par ticularly those moving up and down.

In the embodiment shown, the parts moving up and down are accordingly guided along the machine frame 26 on which the slide 2l which carries the spindle rail i is guided by the sleeve 28. The slide 21, shaft I3, and spindle rail 'l reciprocate as a unit. The mechanism effecting this movement does not form a part of the present invention and may be of the type described in my U. S. Patent No. 2,658,327.

it is particularly important to have the breathing power of the machine take up any dimensional changes which may possibly be caused by the specific up and down motion of the vertically movable parts. As a result of the vertical movement, there are dynamic stresses and abrasions which may lead to dimensional changes affecting the functional accuracy, To eliminate these, it is suggested that the actuating mechanisms for the up and down motion of the parts concerned should also be located in the planes A--A of the joints. In the embodiment illustrated, this has been accomplished by locating the driving element for the slide 21, viz. the lifter wheel 29 actuating the lifter nut 29', in the plane A-A.

According to the invention, the longitudinal sections are connected to each other in an articulated manner. This can be accomplished in various ways, and the constructive means to achieve this are well known. It is particularly advantageous to unite all the longitudinally divided parts having a circular cross section by means ,of uniform coupling elements, such as are indicated, by way of example, in Fig. l, and on a larger scale in Figs. la and 1b, and which comprise slots 25, 25 provided in two adjacent cylindrical longitudinal parts i3, and the connecting piece 25 belonging thereto. Of course, these connections may be replaced by suitable other coupling means, sleeve couplings, flexible plates, or similar means. It is only essential that they should be alike for all joints in order to ensure a uniform and equal amount of flexibility which guarantees the breathing power of the machine. Apart from this, by making the coupling parts alike, the manufacture thereof is simplified through mass production, and the storing problems are materially reduced since only a very few types of coupling means have to be kept in stock. Besides, a quicker assembly and dismantling is made possible thereby. Non-cylindrical parts may be coupled together in a similar manner.

According to the invention, the individual sections, in addition to being of equal length, are so dimensioned that their expansions due to variations in temperature or varying static and dynamic stresses are nearly constant. Therefore, the cross sections of the individual parts are essentially or approximately the same, depending on the kind of material used, that is to say depending on the linear and volumetric coefficients of expansion.

As will appear from the drawing, the cylindrical longitudinal parts Sand 8 to I3 are of essentially the same diameter and, therefore, have the same prole and the same coemcient of expansion. Negligiblev dimensional differences in the diameters as are inevitable from atechnological point of view do not impair the principle of the present invention.

According to a further development of the invention, also the machine frames 26 are located in the planes A-A of the joints of the longitudinal sections. ln the embodiment of the invention according to Fig. 1, the frame is shown as a column, but the invention is not limited to this shape, although, being universally applicable, it appears to be the most suitable one for the embodiment of the characteristics of this invention.

In accordance with the invention, the longitudinal sections i to I3 are adjustable in height in their entirety by means of the machine frames and the sections of the individual shafts such as shaft i3 are adjustable in height in their entirety by means of the slide 2l. vision, it is easily possible to compensate for any deviations from the horizontal resulting from wear or sinking down of the machine simply by regulating the height of that frame which has sunk, this adjustment being eiected at the same time for all the longitudinal sections without detriment to their parallel position. The height adjustment may be effected by any suitable standard means. In its simplest form, such means may comprise a threaded bolt 3| which engages the nut 30 and is screwed into the machine frame or out of it by the amount desired, as shown in the drawing.

By locating the joints of the individual sections of the longitudinal parts invariably in one and the same plane, as directed, the longitudinal r sections constantly maintain their relative parallel position by virtue of their flexibility. They adjust themselves relative to one another like the links of a chain without any jamming as it occurs with the known types of machines. Figs. 2 and 3 make this evident.

Fig. 2 is a diagrammatic elevational view of a conventional type of machine having longitudinal parts which differ in length. As indicated, the length of the roller beam 32 differs from that of the ring rail 33, and this in turn is different from that of the spindle rail sections 3K3 and drawing rollers 35. Assuming the machine frame 35 has sunk as shown in the drawing by the dashed line, then the longitudinal sections 32 to 35 bend in various ways, similar to the exaggerated illustration indicated by dashed lines, thus causing an irregular running of the machine.

The machine according to this invention reacts difierently in such circumstances. rhis is evident from Fig. 3. Should the sub-soil underneath the machine undergo any change in level, i. e. sink within the area of the column 36, all machine parts will move parallel to each other, as

Due to this proshown by dashed lines.' Due toxthis fact, the

threads remain parallel to each other, and the running of the machine is hardly aiected.` By an early height adjustment whichis to be eiiected by means of the levelling device (not shown) fitted to the machine frame the regular position is restored and the damage is repaired by the means available in the machine.

This comparison demonstrates the difference between the invention and the prior art. From the broken lines, the coarse effects of the diilerent bending moments, although shown exaggerated, are apparent for each of the cases shown.

Referring to the manufacture and assembly, it is an advantage if the longitudinal division according to the present invention is also extended to auxiliary elements such as piping'running in the longitudinal direction of the machine.

By adhering to the technical rules of the present invention, it is not only possible to build machines which adapt themselves better to load variations than hasr been the case with conventional types, but also to build machines of greater length than heretofore possible, because the measures suggested by the invention permit of producing absolutely uniform load diierentials throughout the various sections so that these. load differentials will have a considerably smaller eiect upon the whole structure than the gross differences experienced heretofore.
